PLANNING - Change of Mind

I have filmed footage for Life in the Day of a Student, but after consideration and many attempts to plan the narrative, I have concluded that it is not exciting enough to make into a short film. I do not have access to the sound effects that I had hoped for, and I think if I continue to try and edit the footage, I will end up with a five-minute scene in which nothing really happens, nobody learns anything and that is forgotten about within minutes.
However, due to this change of heart, I have had to plan something to take the place of my original idea. I have decided to produce a teaser trailer instead. The narrative of this new idea contains similar aspects of the original idea, and I may even be able to use some of the original footage due to this. 
The new idea is still based around teenage life, but instead of following one character's day in their hungover state (original plan), I have decided to do a Channel 4, Dispatches-style, documentary trailer displaying the early morning of five or six aspiring students in their home town. The moral of this trailer will be along the lines of "Do students really act the way they're portrayed?" and by showing the faces and routines of the students in the trailer I hope that this will work the way I imagine. 
My initial inspiration for this change was due to this song, which I will use as the song for my trailer; Sigur Rós - Með Blóðnasir
